For Joomla users who are still running websites on version 1.7 and are not planning to upgrade to 2.5, the Joomla! Project has released version 1.7.5 in order to patch an Information Disclosure exploit.

Users are urged to upgrade to version 2.5 as soon as possible as Joomla 1.7 will reach end of life on February 24, 2012.

The Joomla! Project has announced a new security update release for Joomla 1.7 websites. This is only intended for users that for some reason are unable to update to version 2.5.0. Everyone who is able to update to 2.5.0 is strongly encouraged to do so.
